Military EMI/EMC Training

The goal of electromagnetic compatibility (EMC) is the correct operation of different equipment in a common electromagnetic environment.

Military EMC is especially critical – so much so that there are specific military regulations such as MIL-STD-461 and MIL-STD-464.

MIL-STD-461 describes how to test equipment for electromagnetic compatibility. According to IEEE, MIL-STD-461 is a set of requirements intended to serve a wide range of platforms from trucks to ships to aircraft to fixed installations, and many different applications such as above deck and below deck on a Navy ship.

MIL-STD-464 sets out minimal acceptable standards for the electromagnetic compatibility of ordnance and related equipment used in airborne, sea, space and ground-defense systems.

Military standards of EMI/EMC emission and immunity are much higher when compared to commercial applications because there is no room for error or failure.

Harsh weather conditions (lightning, solar flares, floods, earth-quakes) and man-made threats (nuclear explosions, war) on military installations lead to very strict performance and reliability requirements. Testing the equipment on-site is also critical to military usage.

Compliance with MIL-STD-464 requires demonstrating that all aspects of a system are electromagnetically compatible during each stage of their life cycle. This includes storage, transportation and maintenance as well as during normal in-service operation.

MIL-STD-464 certification is typically achieved through EMC/EMI testing in highly controlled, semi-anechoic chambers.

Military applications affected by EMI/EMC are considerable, and include:

  • Military Radio Communication (RF radio transmitters and receivers)
  • Radar Systems (Equipment susceptibility due to close proximity to strong RF fields generated by radar transmitters)
  • Radiated susceptibility from commercial equipment nearby
  • Satellite Systems (Communication and Positioning)
  • Remote explosive devices
  • Cognitive radio networks
  • Aircrafts, Ships and Submarines

Military EMI/EMC Training Course by Tonex

Military EMI/EMC Training, a 3-day comprehensive training covers the theory of EMC/EMI and all aspects of MIL-STD-461 and MIl-STD-464.

Military Electromagnetic Compatibility (EMC/EMI) Training Program is applicable to engineers, technicians, analysts and managers interested in the military EMC fields such as: bonding, shielding, grounding, EMI prediction, EMI analysis, conducted and radiated interference, lightning protection and more.

The 3-day military EMI/EMC training covers the basic math and the physics of EMI/EMC and the fundamentals of instrumentation, instruments, test setups, and real measurements.

Military Electromagnetic Compatibility (EMC/EMI) is designed for anyone work on advanced technology systems, complex system of systems (SoS) and components in military applications. End-to-end testing helping you ensure the electromagnetic compatibility of your equipment & subsystems to any version of MIL-STD 461 and MIL-STD 464.

With over 25 years of MIL-STD testing training and consulting experience, we prepare you to evaluate your equipment and subsystems to extreme electromagnetic conditions to ensure the electromagnetic compatibility (EMC) and mission readiness of your equipment is performed correctly. Our streamlined testing process techniques keeps lead time to a minimum.

Achieving electromagnet compatibility compliance performance of equipment and systems is essential to ensure the safety, reliability and availability of the equipment in its intended installation environment: military procurement contracts specify the level of EMC performance required (usually in reference to test standards such as Defense Standard 59-411, MIL-STD 461)

The purpose of the Military EMI/EMC Training Program is to foster technical “excellence” in military EMC engineering. This approach establishes technical competency criteria for EMC and enforces these criteria for technical personnel performing EMI control work.
